AFP-3030 Operations Manual — P/N DOC-01-039:A 26/11/2015 36
Direct Brigade Access (DBA) Event Operation of the Control Panel
How the Panel Indicates a Output Delay
When an initiating device participating in Output Delay goes into alarm, the panel LCD displays a
fire alarm message. (Refer to Section 2.2, “Fire Alarm Event”, on page 16.) If a second alarm
occurs while the Output Delay timer is counting down, the control panel aborts the Output Delay
timer countdown and activates all programmed outputs. The fire alarm LED flashes and the panel
sounder pulses a steady tone. The control panel latches until the alarm is corrected and the
SYSTEM
RESET
key is pressed to reset the panel.
How to Respond to a Output Delay Alarm
Once the Output Delay timer has begun counting down, the operator has the duration of the count-
down time to respond to the alarm before the control panel automatically activates all outputs with
ZF0 in their zone map and CBE linkage to the alarm. The operator can reset the panel if the alarm is
determined false.
2.13.3 Heavy Loads Output Delay
The NAC Outputs on the control panel’s PSI board and modules programmed as ALARM DEV Type
ID code are automatically delayed for 2 seconds.
Heavy loads, such as alerting devices that use the same power source as the control panel, shall be
used with heavy load output delays to meet Standards requirements.
2.14 Direct Brigade Access (DBA) Event
2.14.1 How the Control Panel Indicates a DBA point is active
The panel uses Logic Zone ZL920 to determine if a point with Type ID of DBA is activated. Acti-
vation of a DBA point causes the control panel to do the following:
• Logic Zone ZL920 is activated.
•The
MUTE ALARM DEVICES button will not silence the alarm devices.
• The Silence Alarms Bulgin Switch will not silence the alarm devices.
• If the Silence Alarms Bulgin Switch is restored from silence while Logic Zone ZL920 is
active, the active alarms will not be disabled.
•The
OPERATION LED on the keypad will be off.
•The
SYSTEM NORMAL LED on the ACM-ZM will be off.
• If the alarm devices are disabled, the alarm devices will not activate. When the alarm devices
are enabled, the alarm devices will activate if Logic Zone ZL920 is still active.
• Does not light the
ALARM DEVICES TEST LED on the keypad.
•The
ALARM DEVICES TEST button will be disabled.
•The
ALARM DEVICES DISABLE button will still disable the alarm devices.
2.15 Complementary Features
2.15.1 Door Switch
The door switch alerts Building Managers that the SGD has been isolated and/or the panel has been
silenced; in such a scenario, there is the possibility that building occupants and the Fire Brigade
will not be made aware of an emergency.
An Interlock Fault will arise if:
• The panel is silenced, and/or;
NOTE: To activate the NAC outputs on the PSI from a DBA activation, logic zone 920 must be
included in their CBE.
